EGG-CARTON.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed June 3, 1907. Serial No. 377,089.

To all whom it may concern:

Be it known that I, HonAoE W. JANIOKE, a citizen of the United States,residing at Augusta, in the county of Butler and State of Kansas, haveinvented a new and useful Egg-Carton, of which the following is aspecification.

This invention relates to egg cartons.

The object of the invention is to provide a cheap, durable andthoroughly efficient form of carton, in which the parts shall be capableof being quickly assembled for use and be held combined in such manneras to secure the maximum rigidity and in which the interior shall bedevoid of projecting parts, thereby to facilitate the positioning of theegg holders or grids therein.

With the above and other objects in view as will appear as the nature ofthe invention is better understood, the same consists in the novelconstruction and combination of parts of an egg carton, as will behereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification and inwhich like characters of reference indicate corresponding parts,Figure 1is a view in plan exhibiting the blank of the carton. Fig. 2 is aperspective view of a carton constructed from the blank shown in Fig. 1.

The carton is made from a sheet of card or paste board of any desiredthickness and is formed by cutting or stamping into the shape shown inFig. 1. The blank provides a bottom 1, two side walls 2, two end walls3,

each of which includes a tucking flap 4, a guard 5 formed by a three-cutslit 6, and a pair of keepers 7, four corner flaps 8, each of whichincludes a locking tongue 9 and two cover members 10 and 11, the formerof which is provided with a crescentic slot 12 to be engaged by a tongue13 carried by an extension 1 1 on the latter.

The keepers 7, as clearly shown in Fig. 1, constitute angular extensionsof the tucking flaps, and operate in a positive manner to prevent thelatter from working upward when bent over the end walls, as shown inFig. 2, as such movement will be prevented by the frictional contactbetween the side Walls and the keepers. In the eventthat the flapsshould work upward until they contact with the under sides of the covermembers, the keepers, owing to the increased width they impart to theflaps, will prevent the latter from having any endwise movementrelatively to the carton which would result in their disconnection.

The guards 5 that are formed by the slits 6, are of greater Width thanthe tongues 9, so that when the arts of the box are assembled, as shownin ig. 2, the said guards will extend above the upper edge of the endwalls and thus form steps which will prevent inward movement of itswalls as from strains or pressure.

The locking tongues 9 are formed by cutting away a portion of the cornerflaps adjacent to the cover members 10 and 11, as shown at 15, and thesetongues are of a width approximating the length of the slits 6, so thatwhen projected therethrough, as shown in Fig. 1, they will be securelyheld in place.

In setting up the box, the side walls are folded on the dotted lines A,B, thereby defining the bottom, and when the side walls are thuspositioned the corner flaps 8 are bent inward on the dotted lines E, F,G and H, thereby to bring them to the position to form a portion of theend walls, and the end walls 3 are then bent upward on the dotted linesC and D. This brings the slits 6 over the guards 5 and tongues 9, andthese are then caused to project through the slits, after which thetucking flaps are turned over the upper edges of the end walls andcorner flaps and positioned as shown in Fig. 2, the bending of the flapsbeing along the dotted lines I and J. In positioning the flaps, thekeepers 7 are forced into the corners formed by the juncture of'the sidewalls and end walls, and are thus securely held in position. The covermembers are then folded over on the dotted lines K and L to the positionshown. These dotted or folding lines may be either ordinary scores orspaced dashes formed by a suitable implement.

When the box is assembled in the manner described all the parts will bepositively combined and will be held against accidental separation inuse. I

While the carton is herein described as adapted for use for the holdingof eggs, it is to be understood that it may be employed for otherpurposes, as for candy receptacles,

tural arrangement.

What is claimed is 1. A carton having inturned corner flaps providedwith looking tongues, and end Walls provided with slits through whichthe tongues without any change whatever in the struc- 1project and withtucking flaps embodying eepers coaoting with the side walls of thecarton to hold the flaps in operative position. 2. A carton havinginturned corner flaps 5 provided with looking tongues, and end wa lsprovided with slits through which the tongues roject and with tuckingflaps embodying eepers coacting with side walls of the carton to holdthe flaps in operative position 10 and with guards to brace the endwalls against inward yielding.

3. A carton having inturned corner flaps provided with locking tongues,and end walls provided with slits through which the tongues project andwith tucking flaps embodying 15 In testimony that I claim the foregoingas 20 my own, I have hereto aflixed my signature in the presence of twowitnesses.
